I MPROVED DEVICE FOR REVRSING' MOTION.

The Schedule referred to in these Letters Patent and making part of thename.

To all whom it may concern Be it known that I, CHARLES F. HADLEY, ofChicopee, inthe county of Hampden, and State of vlVIassachusetts, haveinvented a new and improved Device i lfor Reversing Motion; and I dohereby declare that 'lhe object 'of this invention is to overcome deadpoints in machinery where continual reciprocating mo tion is required..l

' The projection A is cast upon the steam-cylinder,

forming a recess for the crank-lever F andthe stirrup G, upon whichisbolted the `plate B, securing the crank-lever pin M. i l i Upon theplateB is forged the Stud 1 for thc main lever H, Connectingwith theside rod T.

Upon the cam K is fitted the stud J for the stirrup G, connecting thecam K with the crank-lever F, also the lugs S S, communicating with thelever H.

The cam K is fitted to the valve-spindle L.

The spring cylinder C is secured to itsplace, in which `is fitted towork freely the piston D ,through which is made the mortis Q for thelcrank-lever F.4

The piston D is forced back by the Spiral spring E, and both secured bythe nuts o o.

The slot R,'through the spring cylinder C, is oi Sutficient length toallow the free motion of the cranklever F. l

The small valve P through the nut o for the admission of air when thepiston is drawn forward, and closed when the piston is thrown back,forming a cushiontoprevent sudden concussion.

e To operate'this device, move the lever.H until it Strikes one of thelugs S S on the cam K, moving it until the cani has passed the center,bringing the spiral spring E in operation, when the. valve is thrownover and the n1achine is reversed.

By this device the same motion of 'the Spring E gives a reverse motionto the cam.

Although this invention has been described as ap-V plied to a valve, yetI do not design limiting its application to this device., but intend toapply it to-any machine in which a reciprocating movement isproduced,'as, for example, planing-machines, &c.

Having thus described my invention, `What Iclaim as new, and desire tosecure by Letters Patent, is

1. The spring cylinder C, the piston D, in combina,-` ytion with thecrank-lever F and the stirrnp G, in the manner and for the purpose setforth.

2. The employment of the spiral spling E, or its equivalent, incombination with the parts above described, operating substantially asdescribed and for the purpose herein set forth. l
